- Each adjustment mechanism further includes an adjustment drive shaft 40, arranged in perpendicular relationship to the arm adjustment shaft 38.
- a right-angle drive coupling operatively connects each drive shaft 40 with the respective arm adjustment shaft 38.
- the right-angle drive coupling comprises a worm 42 mounted for rotation on adjustment drive shaft 40, and a work gear 44 mounted on arm adjustment shaft 38, in meshing engagement with worm 42.
- An adjustment sprocket 46 is mounted on the adjustment drive shaft 40 for effecting operation of the adjustment mechanism, as will be described.
- Adjustment of the adjustment mechanisms is effected by the provision of an adjustment drive chain 48 which extends about the sprocket assemblies of the apparatus in parallel relationship to the conveyor chains 24. Adjustment of the support arm spacing is effected by an arrangement which moves the adjustment drive chain relative to the conveyor chains 24 about the sprocket assemblies.
- Each of the sprocket assemblies includes at least one conveyor chain sprocket in respective engagement with the conveyor chains 24, with two such sprockets being provided on each of the sprocket assemblies in the illustrated embodiment.
- Each of the sprocket assemblies further includes an adjustment sprocket in engagement with the adjustment drive chain 48.
- Adjustment of the apparatus is achieved by providing sprocket assembly 22 with a pair of coaxial shafts, one of which is joined to a respective sprocket in engagement with the adjustment drive chain 48, and the other of which is joined to respective sprockets in engagement with conveyor chains 24.
- the adjustable sprocket assembly 22 of the present apparatus includes an outer shaft 50 arranged in coaxial relationship with an inner shaft 52.
- a pair of conveyor chain sprockets 54 are mounted on the outer shaft 52 for rotation therewith, with each of the sprockets 54 being configured for respective engagement with the conveyor chains 24.
- Apparatus adjustment is achieved by the provision of an adjustment drive sprocket 56 fixed to inner shaft 52, with the sprocket 56 being in engagement with adjustment drive chain 48.
- An adjustment handle 58 is connected to the inner shaft 52 for effecting rotation of the inner shaft, and thus adjustment drive sprocket 56, relative to drive sprockets 54.
- a suitable drive motor can be optionally provided for effecting relative rotation of the inner and outer shaft. In this manner, adjustment drive chain 48 can be moved relative to the conveyor chains 24.
- a selectively engageable shaft lock 60 comprising a lockable collar, is mounted on outer shaft 50, and is operable to lock the outer shaft 50 and the inner shaft 52 against relative rotation.
- each of the sprocket assemblies of the apparatus includes a sprocket in engagement with the adjustment drive chain 48 which can rotate relative to the associated sprockets about which the conveyor chains 24 are trained. Movement of adjustment drive chain 48 relative to the conveyor chains 24 acts through sprocket 46 of each adjustment mechanism of each holding assembly 26.
- Adjustment drive shaft 40 of each adjustment mechanism is thus rotated, whereby worm 42 effects driven rotation of the associated worm gear 44.
- Rotation of arm adjustment shaft 38 is thus effected, with the oppositely threaded end portions of the shaft to which support arms 36 are coupled effecting movement of the support arms toward or away from each other.
- the shaft lock 60 on sprocket assembly 22 can be tightened to fix outer shaft 50 and inner shaft
